DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1-12 depict a connector 1 that is capable of withstanding vibration or other external forces without uncoupling. The connector 1 may also be referred to as an adapter or a coupler. The connector 1 may be used in various applications, such as a fluid application or an electrical application. Although not shown herein, the connector 1 is configured to be mated to a mating connector, such as the mating connector 104 shown in U.S. Pat. No. 9,528,646 to ITT Manufacturing Enterprises LLC. U.S. Pat. No. 9,528,646 (the '646 Patent) is incorporated by reference herein in its entirety and for all purposes.

Unless otherwise specified, each of the components of the connector 1 has a substantially cylindrical shape that is revolved about a longitudinal axis ‘A’ and each of the components has a substantially hollow interior. Also, as used herein, the term ‘distal’ refers to a position either at or toward a first end 2 a of a connector body 2, and the term ‘proximal’ refers to a position either at or toward the second end 2 b of the connector body 2. The phrases ‘inner,’‘inside facing’ or ‘interior facing’ refer to a surface or feature that faces toward the longitudinal axis ‘A’, while the phrases ‘outer’, ‘outside facing’ or ‘exterior facing’ refer to a surface or feature that faces away from the longitudinal axis ‘A’.

Referring now to FIGS. 1-5 and 11, the connector 1 includes a connector body 2 upon which the remaining components of the connector 1 are mounted either directly or indirectly.

Connection means 2 c are provided on the outer surface of the first end 2 a of the connector body 2 for releasably mating with a backshell. (not shown) or a strain relief (not shown), for example. According to this exemplary embodiment, the connection means 2 c are male mechanical threads. The connection means 2 c could be, for example, female mechanical threads, a bayonet connection, a clip, a clamp, a fastener, a post, a prong, a spring, a ring, a friction fit, or an adhesive.

The second end 2 b of the connector body 2 includes a series of axially-extending lugs 2 d that are slidably positioned within axially-extending channels 105 (one shown) of the mating connector 104 shown in the '646 Patent. Engagement between the lugs 2 d and the channels 105 permit axial translation, yet prevent relative rotation, between the connector body 2 and the mating connector 104. It should be understood that the connector body 2 could include the channels and the mating connector 104 could include the lugs to achieve the same result.

A series of gear teeth 4 extend radially outward from the outside facing surface of the connector body 2, and are uniformly positioned about the circumference of the connector body 2. The teeth 4 may be positioned about the entire circumference of the connector body 2. The fillet, face and flank of each tooth 4 extend in an axial direction along the longitudinal axis A. As will be described later, a series of springs 6 are configured to interact with the gear teeth 4.

The connector body 2 also includes a recess 5 formed on its outer surface in which a retaining ring 3 is fixedly positioned. The recess 5 is positioned at an axial location between teeth 4 and connection means 2 c.

The interior region of the connector body 2 includes components 11 comprising a dielectric material and electrical contacts for establish an electrical connection with mating connectors. Alternatively, the interior region of the connector body 2 may be hollow and the hollow space may be used to accommodate a cable (not shown) passing therethrough, for example. The cable may contain one or more wires or a passage for fluid for example. As another alternative, the hollow interior region of the connector body 2 may be used for the passage of fluid.

As best shown in FIG. 5, an inner sleeve 9 is mounted to the outer surface of the connector body 2 such that, in the unlocked state of the connector 1, the inner sleeve 9 is capable of rotating freely in clockwise and counterclockwise directions on the surface of the connector body 2. The inner sleeve 9 is radially positioned between an outer sleeve 8 and the connector body 2. An inwardly extending shoulder 9 a at the distal end of the inner sleeve 9 that is axially positioned between the teeth 4 of the connector body 2 and a spring retainer 7. Both the inner sleeve 9 and the spring retainer 7 are limited from translating along the longitudinal axis “A,” with respect to the connector body 2, because those components are sandwiched between the ring 3 and the distal face of the teeth 4 of the body 2.

The connection means 17 are provided on the inside facing surface of the inner sleeve 9 for releasably mating with the connection means 106 of the mating connector 104 of the '646 Patent. Upon mating the connector 104 with the connector 1, the connector 104 is at least partially positioned within the annular space 19 that is defined between the body 2 and the inner sleeve 9. According to this exemplary embodiment, the connection means 17 and 106 are mechanical threads. The connection means could be, for example, a bayonet connection, a clip, a clamp, a fastener, a post, a prong, a spring, a ring, a friction fit, or an adhesive.

A series of four circular through holes 16 are defined on the exterior surface of the inner sleeve 9 at a location distal of connection means 17. As best shown in FIG. 4, the holes 16 are uniformly spaced about the circumference of the inner sleeve 9. The holes 16 are also axially aligned along the longitudinal axis A. In an assembled from of the connector 1, a ball 20 (also referred to herein as a moveable member) is positioned within each hole 16.

As best shown in FIGS. 4 and 11, a series of four holes 22 are defined on the distal face of the inner sleeve 9. Each hole 22 terminates at a cutout 22 a, which is formed on the interior facing wall of the inner sleeve 9. Each hole 22 extends parallel to the longitudinal axis A. The holes 16 are equally spaced in a radial direction from the longitudinal axis A, and are uniformly spaced apart by 90 degrees about the longitudinal axis A.

In an assembled form of the connector 1, a single pin 23 is positioned within each hole 22, and a hinge 6 a of a spring 6 is rotatably positioned within respective cutouts 22 a. The small-diameter end of each pin 23 is positioned through the hinge 6 a of a respective spring 6 so as to captivate the hinge 6 a in a respective cutout 22 a of the inner sleeve 9.

The outer surface of the inner sleeve 9 includes an outwardly extending shoulder 9 b. The proximal end of the outer sleeve 8 is configured to abut the distal facing surface of the shoulder 9 b. The shoulder 9 b includes three sets of adjacent openings 14 a and 14 b (six total openings) and one set of openings 14 a′ and 14 b′ (two total openings) that extend in an axial direction through the shoulder 9 b. The sets of adjacent openings 14 a/14 b and 14 a/14 b′ are uniformly spaced about the circumference of the shoulder 9 b. Each opening 14 a and 14 b is sized and positioned to receive a post 15 extending from the proximal face of the outer sleeve 8, and each opening 14 a′ and 14 b′ is sized and positioned to receive a post 15′ extending from the proximal face of the outer sleeve 8. The outer sleeve 8 includes three posts 15 and one post 15′. Each post 15 is capable of mating with only one opening (i.e., either opening 14 a or opening 14 b) of a single set of adjacent openings 14 a and 14 b at any one time; and, post 15′ is capable of mating with only one opening (i.e., either opening 14 a′ or opening 14 b′) at any one time, as will be described in greater detail later.

The first set of adjacent openings 14 a′ and 14 b′ is different from the remaining three sets of adjacent openings 14 a and 14 b. More particularly, the first set of adjacent openings 14 a′ and 14 b′ are positioned further from the longitudinal axis A than the remaining three sets of adjacent openings 14 a and 14 b. Also, the first set of adjacent openings 14 a′ and 14 b′ are recesses formed on the outermost surface of the shoulder 9 b, whereas the remaining three sets of adjacent openings 14 a and 14 b are circular holes formed through the thickness of the shoulder 9 b.

Because the first set of adjacent openings 14 a′ and 14 b′ are positioned at a different distance from the longitudinal axis A than the remaining three sets of adjacent openings 14 a and 14 b, the inner sleeve 9 is keyed to the outer sleeve 8 so that each post 15 is assigned to a single set of openings 14 a and 14 b. It follows that the post 15′ is assigned to, and can only mate with, the first set of openings 14 a′ and 14 b′. It also follows that the post 15′ is positioned further from the longitudinal axis A than the remaining three posts 15.

Referring now to FIGS. 5 and 11, the outer sleeve 8 is a substantially cylindrical body that substantially surrounds and encloses the inner sleeve 9, the connector body 2 and the spring retainer 7. In use, the outer sleeve 8 is configured to translate along the longitudinal axis A, and, upon being translated in the distal direction, the outer sleeve 8 is configured to rotate about the inner sleeve 9. The outer sleeve 8 may be configured to rotate about the inner sleeve 9 to a limited degree and only between the positions shown in FIGS. 4 and 9. Alternatively, the outer sleeve 8 may be configured to rotate about the inner sleeve 9 by three-hundred and sixty degrees and without restriction.

The outer sleeve 8 includes a knurled revolved outside facing surface for grasping by a user. Those skilled in the art will recognize that the outside facing surface of the outer sleeve 8 may have other features for facilitating grasping by a user. The revolved outside surface of the outer sleeve 8 may include indicia identifying the locked and unlocked positions of the outer sleeve 8.

As noted above, the outer sleeve 8 includes a set of three posts 15 that are configured to engage the openings 14 a and 14 b, and one post 15′ that is configured to engage the openings 14 a′ and 14 b′. As best shown in FIG. 11, each post 15 extends outwardly from the proximal end 27 of the outer sleeve 8. Each post 15 may be cylindrical in shape. The posts 15/15′ are radially spaced about the circumference of the outer sleeve 8 in a uniform manner (i.e., separated by ninety degrees). The post 15′ is specially configured to engage only with openings 14 a′ and 14 b′. The post 15′ is positioned further from the longitudinal axis A than the remaining three posts 15, however, those skilled in the art will recognize that other solutions exist for keying the outer sleeve 8 and the inner sleeve 9.

Referring now to FIGS. 9 and 10, a series of four rectangular-shaped recesses 26 are formed on the inside facing surface of the outer sleeve 8. Each recess 26 extends between the proximal end 27 and a shoulder 8 a of the outer sleeve 8. The recesses 26 are radially spaced about the circumference of the outer sleeve 8 in a uniform manner (i.e., separated by ninety degrees).

The shoulder 8 a is formed on the inside facing surface of the outer sleeve 8 and extends inwardly. In an assembled form, the shoulder 8 a is positioned to abut the distal end 28 and shoulder 9 a of the inner sleeve 9. An annular recess 25 is formed between the distal facing surface of the shoulder 8 a and the proximal facing surface of the spring retainer 7.

A wave spring 10 is positioned within the annular recess 25. The shoulder 8 a is configured to translate within the recess 25 against the bias of the wave spring 10. More particularly, the outer sleeve 8 is configured to translate along the longitudinal axis A and in a distal direction by a predetermined amount with respect to the inner sleeve 9 and the spring retainer 7 against the bias of the wave spring 10.

As best shown in FIG. 4, a series of four springs 6 are mounted to the interior face of the inner sleeve 9. Although only one spring 6 will be described hereinafter, it should be understood that each spring 6 shares the same structure and function. Additionally, the spring 6 may vary from that which is shown and described and may be referred to herein more generally as a releasable locking member.

The spring 6 includes an elongated body formed of an elastic material, such as spring steel. A hinge 6 a is provided at one end of the elongated body. As noted above with respect to FIGS. 4 and 11, the hinge 6 a is mounted in a respective cutout 22 a, which is formed on the interior facing surface of the inner sleeve 9, by the small diameter end of the pin 23. The hinge 6 a may be capable of pivoting about the small diameter end of the pin 23.

As best shown in FIGS. 11 and 12, a bend formed in the center of the spring 6 forms a tooth 6 b of the spring 6. In an assembled form of the connector 1, the tooth 6 b of the spring 6 engages with the gear teeth 4 of the connector body 2 to control rotation of the inner sleeve 9, as will be described with respect to operation of the connector 1.

The connector 1 includes four balls 20 that are each positioned in respective holes 16 of the first sleeve 9. Each ball 20 has a diameter that is greater than the thickness of the first sleeve 9. Each ball 20 could be replaced by a small cylinder or other member, if so desired. For that reason, a ball 20 may be more generally referred to hereinafter as a moveable member.

The connector 1 includes four releasable locking assemblies that operate together in unison to control rotation of the inner sleeve 9 about the connector body 2. Each releasable locking assembly includes one spring 6, one ball 20, one hole 16 and one recess 26. It should be understood that the number of releasable locking assemblies may vary from that which is shown and described. Also, although not shown, the spring and ball may be integrated together into one single resilient locking component.

Referring now to the operation of the connector 1, starting from the unlocked state shown in FIGS. 6-10, the unlocked connector 1 is connected to the mating connector 104 of the '646 Patent by performing the following steps: (a) manually aligning the lugs 2 d of the body 2 within respective channels 105 of the mating connector 104 of the '646 Patent (not shown herein); (b) manually engaging the connection means 17 of the inner sleeve 9 with the connection means 106 of the mating connector 104; (c) manually rotating the outer sleeve 8 (which in turn rotates the inner sleeve 9 due to engagement between the posts 15 and the openings 14 a) in a tightening direction, consequently engaging the connection means 17 of the inner sleeve 9 with the connection means 106 of the mating connector 104; and (d) moving the outer sleeve 8 to the locked position in order to prevent inadvertent unlocking of the connector 1.

During rotation step (c), the springs 6 rotate about the connector body 2 along with the sleeves 8 and 9. In the unlocked state of the connector 1, the recesses 26 of the outer sleeve 8 are radially aligned with respective holes 16 in the inner sleeve 9. As the inner sleeve 9 rotates about the body 2, the tooth 6 b of each spring 6 moves along the toothed surface 4 of the body 2 (the body 2 remains stationary). The springs 6 flex outwardly toward the outer sleeve 8, as each tooth 6 b of the spring 6 moves from one tooth 4 on the body 2 to the next tooth 4 on the body 2. As the springs 6 flex outwardly, the springs 6 push the balls 20 outward and into their respective recesses 26. Stated differently, the clearance space provided by the recesses 26 permit the springs 6 to flex outwardly, which permits the teeth 6 b of the springs 6 to slide along the toothed surface 4 as the sleeves 8 and 9 are rotated together. It should be understood that, in the unlocked state of the connector 1, the holes 16 and recesses 26 rotate together such that the holes 16, the recesses 26 and the balls 20 are always radially aligned with each other in the unlocked state of the connector 1.

During rotation step (c), the mating connector 104 translates in an axial direction within the annular space 19 and toward the connector body 2 (or vice versa) without rotating by virtue of the keyed engaged between the lugs 2 d and the channels 105. Rotation of the outer sleeve 8 in the tightening direction is possible until the connection means 17 of the connector 1 is fully engaged with the connection means 106 of the mating connector 104. Since the connector 1 is still in the unlocked state at this stage, the outer sleeve 8 (which in turn rotates the inner sleeve 9) may be rotated in a loosening direction, which is opposite to the tightening direction.

During locking step (d), the outer sleeve 8 is retracted (i.e., moved distally) such that the shoulder 8 a moves into the space 25 against the bias of spring 10. Moving the outer sleeve 8 in the distal direction causes the posts 15 to exit and separate from their respective openings 14 a. The outer sleeve 8 is then capable of being rotated relative to the inner sleeve 9. While the outer sleeve 8 remains retracted, the user then rotates the outer sleeve 8 by a small angle until the posts 15 are aligned with the adjacent set of openings 14 b. At this stage, the recesses 26 are misaligned with, or otherwise rotationally spaced from, the holes 16, as shown in FIG. 4. The user then releases the outer sleeve 8, which causes the spring 10 to translate the outer sleeve 8 in the proximal direction (and without rotation). As the outer sleeve 8 moves proximally, the posts 15 enter their respective openings 14 b.

The connector 1 is then maintained in the locked configuration. In the locked configuration, the sleeves 8 and 9 are prevented from inadvertently rotating in a loosening rotational direction with respect to the connector body 2 and the mating connector 104 due to vibration or other external forces. Attempting to rotate the outer sleeve 8 in the loosening or tightening rotational direction while the outer sleeve 8 is maintained in the locked configuration, either purposefully or inadvertently, causes the surfaces of the teeth 6 b and 4 to bear on each other (as opposed to slide past each other), thereby preventing rotation of the outer sleeve 8 and the inner sleeve 9 in the loosening direction with respect to the connector body 2 and the mating connector 104. Unlike the unlocked configuration of the connector 1, the springs 6 are not permitted to flex in the outward direction in the locked configuration of the connector 1 because no clearance space exists for the balls 20 and spring 6 to move outwardly. As noted above, in the locked configuration, the recesses 26 are misaligned with the holes 16 in the locked configuration of the connector 1, thus, no clearance space is provided to accommodate outward movement of the balls 20 and springs 6.

Since the connector 1 is maintained in the locked configuration, it cannot be detached from the mating connector 104 without manual intervention by an end user. Thus, the connector body 2 and the mating connector 104 are each prevented from rotating in the loosening rotational direction with respect to the inner sleeve 9, or vice versa, thereby preventing detachment of the mating connector 104 from the connector 1.

To detach the mating connector 104 from the connector 1, it is necessary to first move the outer sleeve 8 from the locked configuration of FIGS. 1-5 to the unlocked configuration of FIGS. 6-10 by pulling the outer sleeve 8 in the distal direction against the force of spring 10. The user then rotates the outer sleeve 8 by a small angle until the posts 15 are aligned with the adjacent set of openings 14 a. At this stage, recesses 26 are again aligned with the holes 16, as shown in FIG. 4. The user then releases the outer sleeve 8, which causes the spring 10 to translate the outer sleeve 8 in the proximal direction (and without rotation). As the outer sleeve 8 moves proximally, the posts 15 enter their respective openings 14 a.

The user then manually rotates the outer sleeve 8 (which in turn rotates the inner sleeve 9 due to engagement between the posts 15 and the openings 14 a) in a loosening direction, thereby slowly disengaging the connection means 17 of the inner sleeve 9 from the connection means 106 of the mating connector 104. During the rotational step, the springs 6 rotate about the connector body 2 along with the sleeves 8 and 9. As the inner sleeve 9 rotates about the body 2, the tooth 6 b of each spring 6 slides along the toothed surface 4 of the body 2 (the body 2 is stationary). The springs 6 flex outwardly toward the outer sleeve 8, as each tooth 6 b moves from one tooth 4 of the body 2 to the next tooth 4 of the body 2. As the springs 6 flex outwardly, the springs 6 push the balls 20 outward into their respective recesses 26. Eventually, the connection means 17 of the inner sleeve 9 separate and detach from the connection means 106 of the mating connector 104.

Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention.
